To all whom it may concern: I

Be it known that I, JOHN J. WIENs, a citizen of the United States,residing at Quincy, in the county of Douglas and State of Washin 'ton,have invented a new and useful Watch-Regulator, of which the followingis a specification.

This invention relates to improvements in hair spring regulators forwatches, clocks, and other time pieces.

It has for its object to rovide an improved simple and comparative yinexpensive'regulator bar that can be readily applied to almost anywatch, clock or other time piece.

Another object is to provide an improved mechanism simple inconstruction and effective in result, such as can be readily operated toeither increase or diminish the vibrations of the hair spring whendesired to so regulate the movement.

It is well known that most high class regulators now in use areexceedingly expensive due to the-large number of parts employed in theirconstruction.

The present invention is designed to reduce the number of parts requiredfor a high class regulator to the minimum, and at the same time toproduce a construction which will increase or diminish the vibrations ofthe hair spring to the smallest fraction, thus doing the work of thefinest regulator.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinafter fully described, illustrated inthe accompanying drawings, and particularly pointed out in the appendedclaims, it being understood that various changes in the form,proportions, size and minor details of the structure may be made withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the accompanying drawings :Figure 1 is a plan view of the deviceapplied to the hair spring of a clock. Fig. 2 is a similar view of thedevice applied to the bridge of a watch. Fig. 3 is a transversesectional view taken on the line 83 of Fig. 1. Fig. 4 is a detailperspective view of the stud. Fig. 5 is a plan view of the regulatinglever. Fig. 6 is a side view of the same. Fig. 7 is a perspective viewof the adjusting screw.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

In the construction illustrated in Figs. 1 and 2, the balance wheel 1,hair spring 2, and escapement 3 are of a well known type, and form nopart of this invention.

In the present construction, a regulating lever 5 is illustrated, formedof suitable metal, and having one end thereof flattened, as shown at 6.This flattened portion is centrally provided With a transverseperforation for the reception of a shaft 4. The lever 5 is keyed on theshaft 4 and the latter extends beyond the inner face of the lever, andprojects through and is adapted to turn in an opening in the frame 7.

A collar 8 formed integral with or otherwise secured to the frame isadapted to encircle the projecting section of the shaft 4 and the latteris secured therein by a set screw 8 as illustrated in Fig. 3.

Adjacent the end of the lever 5 opposite the flat portion 6 is anelongated slot 9 forming a seat for the clamp screw 10 which fits intoan opening formed in one end of the bar connecting stud 11.

Adjacent the outer end of the stud is a transverse opening 12 of a widthsufficient to accommodate the free end of the hair spring 2, and thelatter is secured in the opening by means of the usual wedge 13.

With the construction thus far described, it is obvious that in order toregulate the movement, the screw 8 is first turned to the left, whichloosens the stem 4 in its seat. The end of the stem projecting beyondthe outer face of the lever is then turned to the right or left, as maybe required to adjust lever 5, and when sufficiently turned is locked bytightening the screw 8 In the construction illustrated in Fig. 2,wherein the device is applied to a watch, the bridge 14 has a transverseopening and secured to the lower face of the bridge and registering withsaid opening is a collar 18 (Fig. 4). A lever 16 substantially the same,but considerably smaller than the lever 5 is provided on one end with ashaft 19 adapted to fit the openings formed in the bridge and col lar18, and is secured therein by a set screw 20 entering an opening formedin the side of the collar 18. The opposite end of the lever is providedwith an elongated slot forming a seat for a clamp screw fitting into oneend of the hair spring stud 1.7, the opposite end of the latter beingprovided with a transverse opening of a Width suflicient to accommodateone end of the hair spring 21. From the foregoing it is evident that theoperation of regulating the Watch movement is the same as the onereviously described.

hat is claimed is 1. A hair-spring regulator for time pieces, consistingof a shaft clamped in the frame of the time piece, means for adjustingthe shaft in rotative position, a regulator lever arm mounted on saidshaft; a hair spring having one end connected to the end of the leverarm; and means for adj ustably clamping the end of the hair spring onthe lever arm.

2. A hair spring regulator for time pieces,

consisting of a shaft mounted to turn in and projecting thrcmgh theframe of the time piece; a collar, and set screw on said shaft adjustably clamping it to the frame a regulator lever arm mounted on saidshaft, and having a slot at its outer end a hair spring, and anadjusting stud and set screw mounted on the slotted end of the leverarm, and clamping the end of the hair spring there to.

In testimony that I claim the foregoing, as my own, I have heretoajflixed my signature in the presence of two Witnesses.
